Vliv managementu a technologie odchovu telat na výskyt parazitárních onemocnění
PAŘÍZKOVÁ, Petra
Faecal samples were collected from two dairy farms. The influence of management and technology on the incidence of Cryptosporidium and Eimeria infections was investigated. A total of 20 calves from each farm were observed from birth to 16 weeks of age, and faecal samples from each animal were examined weekly. A total of 680 faecal samples were collected and examined. Parasite detection was performed by a combination of standard parasitological microscopic and molecular methods. Infections with C. parvum subtypes IIaA13G1R1 and IIaA17G1R1, C. ryanae subtype XXIc, E. zuernii, E. cylindrica, E. ellipsoidalis, E. bovis, E. auburnensis, and E. subsferica were detected. The cumulative prevalence of C. parvum on the sampled farms was 85 %, and the prevalence of infection was detected at one to four weeks of age. The cumulative prevalence of Eimeria spp. reached 100 % in calves from both monitored farms at 16 weeks of age. Feeding high-quality colostrum with a higher immunoglobulin content reduced the intensity of infections caused by C. parvum. The risk of Eimeria infection increased with the length of time calves remained in the farrowing room when the newborn animals were in contact with older calves. Inadequate technique for raising calves together after weaning resulted in an increased incidence of diarrheal disease.

Reprodukce a management chovu vybraných plemen masného skotu
NÁVAROVÁ, Eliška
The literature review presented in the bachelor thesis focuses on the ma-nagement and characterization of cattle breeding, specifically the Aberdeen Angus, Limousin, and Charolais breeds. The following chapter describes ecological ag-riculture, as the thesis includes companies that breed cattle in organic farming. The upcoming chapter of the thesis centers on the reproduction of beef cattle breeds. The aim of this thesis was to conduct a comprehensive and continuous analysis throughout the year by which to evaluate the level of reproduction and ma-nagement. The practical part focuses on evaluation the course of delivery, pregnancy diagnosis results, weight of calves at birth and weaning, and the results from semen examination. The data for this thesis were collected from six companies using ac-companying lists of cattle, animal husbandry records, and bull spermograms. In the conclusion of the thesis, the results are summarized and evaluated. Companies specializing in Limousin and Charolais breeding include their bulls in herd for approximately two months. The company that focuses on breeding Aberdeen Angus has its bulls in herd for most of the year. More frequent occurrence of difficult births was recorded for the Limousin breed at the Rolnická Skalná company, and their number significantly exceeded the average incidence of complicated births for this breed. A higher incidence of di-fficult births was also analyzed for the Charolais breed at the SPO-ZEM Nový Kos-tel company. The number of difficult births recorded at the company specializing in breeding Aberdeen Angus slightly exceeded the breed's average. The highest success rate of pregnancy was found in the companies SPO-ZEM Nový Kostel, Farmy Třebeň, and Anonymu. The Naturland company achieved unsatisfactory levels of pregnancy rates. Companies breeding Limousin achieved lower birth weights, nonetheless the values were satisfactory. Weaning weights of calves in these companies were suita-ble. Companies focused on breeding Charolais achieved unsatisfactory average birth weight values but excellent weaning weight values. For the Aberdeen Angus breed, satisfactory average weaning weight was achieved for heifers, while the weight of bulls was lower than usual for the breed. From the total of 12 monitored bulls, all were fertile at the beginning of the breeding season, infertility was diagnosed in three bulls, and one bull had a high number of immobile spermatozoa. In these bulls, a treatment was applied, which was found to be effective only in two breeding males after the third collection. Bulls for which the treatment was ineffective were removed from the breeding pro-gram.

The effect of helminth infection on the productivity of beef cattle
BRABCOVÁ, Aneta
The study aimed to observe the effect of the helminth infection on the productivity of beef cattle breeds. Samples of feces were collected from farms in the South Bohemian Region of the Czech Republic from the Highland, Limousine, Aberdeen Angus, Galloway and Beef Simmental breeds. A total of five cattle farms were monitored during the study. Coprological methods confirmed the presence of parasitic nematodes Haemonchus contortus, Ostertagia ostertagi, Trichostrongylus axei, Cooperia spp. and Chabertia ovina. Due to the low prevalence of these parasites in the monitored cattle farms, there was no weight loss nor reduction in production. The results of the study demonstrated 100% effectiveness of the targeted veterinary treatment.

Hodnocení welfare v chovu dojnic
Sovadinová, Simona
Animal welfare enhancement requires specific problems being reliably identified and corrective actions being defined afterwards. This diploma thesis evaluates the level of animal welfare on Czech farms with dairy and dual purpose cattle. The thesis uses the European project Welfare Quality®, which is a tool for a comprehensive assessment of livestock living conditions. WQ® gives the farms one of four final marks – excellent, enhanced, acceptable, and not classified. Most farms in this research were marked as acceptable. The organic farm received the best rating of all farms. Barns were most deprived of animal feeding, while animal housings were rated well. This research considers welfare as a multidimensional complex and also assesses specific aspects of dairy farming.
